spurs ; primaries narrow, with large areole, vein R, from cell, R- from areola, 

 R4 and Rs stalked, from a point with Ra, Mi from just below areole. Mi and Ma 

 from a point, Cu» from angle of cell, 1st and 2nd anal not connected; secondar- 

 ies with S. C. free, R and Mi almost parallel from base of wing to margin, with 

 perpedicular discocellular bar, M. and M3 from angle of cell, Cui from behind 

 "cellula intrusa," which is present on both wings. 



This genus is closest to the European genus Phragmataccia Newin, 

 but an examination of the type (arundinis) showed several points of 

 difference in the venation of primaries ; in arundinis vein Rj is from 

 areole, which is much broader than in atra and connected basally with 

 the "cellula instrusa ;" the abdomen is also produced for a far greater 

 length beyond hind wings, and the thoracic vestiture is entirely hairy.

" $ General color dark smoky gray ; thorax sprinkled with Hghter scales 

 and with blackish markings on hinder portion ; abdomen gray ; primaries thick- 

 ly covered with fine black striations, forming a series of irregular transverse 

 lines across wings ; in basal portion these are closer together, causing a darker 

 appearance ; a narrow black bar at end of cell ; secondaries smoky, lighter at 

 anal angle and inner margin; remainder of wing very finely reticulated with 

 black. Beneath as above ; all black markings obscure except along costa of pri- 

 maries for Yi its length. Expanse, 35 mm.

H. GILENSIS B. & McD. (PI. IV, fig. 3.) 



Hamilcara gilensis Barnes & McDunnough, Ent. News, XXI, 466 (1910). 



"5 Thorax gray, mixed with black, especially on metathoracic segment; 

 base of legs thickly covered with long gray hairs ; abdomen with short silky 

 gray squammation ; primaries gray, shaded with light brown in basal portion of 

 submedian fold ; and with numerous fine black transverse striae which in the 

 outer portion of wing tend to form irregular bands ; from costal margin, at ^ 

 from base, a black bar of variable width, inwardly oblique, extends across cell 

 to cubital vein; a narrow black bar at end of cell extends upward to costa, both 

 bars being parallel ; fringes dusky, checkered with black ; secondaries pure 

 white, bordered by dusky fringes, along the margin of which a few faint 

 reticulations are discernable. Beneath primaries, smoky gray, Hghter along 

 costa and inner margin ; a series of dark spots on costal margin ; striations of 

 upper side faintly reproduced in outer portion of wing ; secondaries as above. 

 Expanse 34-40 mm."
